Mini Contactors for Compact Control Panels & OEM Equipment

KRIPAL manufactures mini contactors from 6A to 16A in 3-pole and 4-pole configurations for space-constrained control panels, lighting control and building automation. The compact frame saves up to 20% DIN rail width compared to standard contactors, making them ideal for high-density OEM machinery, packaging equipment and distributed I/O cabinets where every millimeter of panel space counts. Available with AC and DC coils across standard industrial voltages, with matching AU auxiliary contact blocks for status feedback and control interlock circuits.

Mini Contactor Selection Guide for Space-Constrained Panels

A mini contactor is a high-density electromechanical switching device optimized for industrial enclosures where internal panel space is at a premium. Engineered to handle load currents up to 16A, this compact solution provides precise power management for small induction motors, commercial compressors, and localized auxiliary control circuits in space-critical applications.


Technical Specifications of the Mini Contactor Series

Operational Current: 6A to 16A

Engineered specifically for low-amperage applications, providing reliable, high-density load switching for fractional horsepower motors and sensitive control systems.

Pole Configurations: 3P and 4P

Standard 3-pole design for three-phase motor control, with 4-pole variants available for comprehensive circuit isolation, including neutral switching.

Control Coil Versatility

Integrates a full range of AC coil voltages—including 24V, 110V, 220V, and 380V—to ensure native compatibility with global automation control systems.

AU Accessory Integration

Supports tool-free, snap-on installation of AU auxiliary contact blocks, enabling real-time status feedback for integrated logic controllers.

ISO 9001 Certified Manufacturing

Manufactured under rigorous ISO 9001 quality management protocols. These miniature units are built using the same heavy-duty production architecture as our full-size UKC series, ensuring consistent, industrial-grade reliability across the entire contactor family.

4 Systematic Steps to Specify Your Mini Contactor

  1. Calculate the Load Current: Assess the continuous amperage draw of the target equipment to select the precise 6A, 9A, 12A, or 16A hardware rating.
  2. Determine Pole Requirements: Utilize a 3-pole (3P) configuration for standard motor mains, or specify a 4-pole (4P) module when complete neutral conductor disconnection is required by local codes.
  3. Match the Control Circuit Voltage: Align the internal coil specification strictly with the designated control power supply to ensure rapid magnetic actuation.
  4. Configure Status Feedback Logic: Evaluate the automation circuit requirements and add a snap-on AU auxiliary block if the system architecture dictates real-time run or stop signaling.

Compact Control: Mini Contactors in OEM and Building Automation

KRIPAL mini contactors serve space-constrained control applications where standard frame contactors consume too much DIN rail width, from densely packed OEM machine panels and building management enclosures to distributed I/O cabinets on factory floors.

Packaging and Labeling Machine Control

Mini contactors fit the tight DIN rail real estate inside flow-wrapping, cartoning, and labeling machinery where every millimeter of panel width is budgeted and a standard contactor would force a larger enclosure with higher IP rating costs.

Commercial Building Lighting and Blind Control

Mini contactors switch lighting zone circuits, motorized blind groups, and HVAC damper actuators in building automation panels where dozens of contactors share one enclosure and low coil heat dissipation prevents thermal buildup inside sealed cabinets.

PLC to Field Device Interface Panels

Mini contactors serve as the interface layer between PLC transistor outputs and solenoid valves, small motor loads, and signal lamps in distributed I/O cabinets. Low coil burden reduces power supply sizing and thermal management requirements in sealed field enclosures.

Shrink Your Panel, Not Your Options

  • Maximize Panel Density: Reduce your footprint with our 45mm-wide mini contactors (compared to the 55mm standard frame). This saves significant enclosure volume and reduces material costs in high-density control panel designs.
  • Application Suitability Review: Avoid design risks by leveraging our engineering support. We verify mini contactor compatibility with your specific load types, switching frequencies, and ambient temperature requirements before you finalize your panel layout.
  • Strategic OEM Partnerships: Benefit from factory-direct pricing on production volumes, supported by coordinated delivery schedules and consolidated logistics to streamline your complete Bill of Materials (BOM).

Mini Contactor Supply: Volume Flexibility Without MOQ Barriers

KRIPAL mini contactors are manufactured on the same production lines as our standard UKC series, utilizing identical silver-alloy contact technology and coil-winding standards. The key distinction is our purpose-designed, compact frame, which reduces DIN rail footprint by 20%—delivering high-density efficiency without compromising switching performance.

Uniform Contact Technology

Mini and standard contactors utilize the same in-house developed silver-alloy contact formulations. Standardizing on KRIPAL ensures consistent contact life characteristics and simplified maintenance across your entire product line.

DIN Rail Density Advantage

By reducing the footprint from 55mm (standard) to 45mm (mini), a bank of 10 units saves 100mm of rail space. This allows you to either add two extra devices or downsize the enclosure, directly reducing steel costs and IP-rating expenses.

Optimized Logistics & Freight

Combine mini and standard contactors into a single purchase order. Our logistics team optimizes pallet utilization to prevent the inflated per-unit freight costs typically associated with split-vendor orders.

Flexible Procurement (Low MOQ)

While major manufacturers often mandate 200+ unit minimums, KRIPAL supports specialized builders with order quantities starting at just 30 units. We provide the compact components you need, without the commodity volume requirements.

Ready-to-Install Assemblies

Order mini contactors with AU auxiliary blocks pre-mounted as a single SKU. Your assembly team receives a ready-to-install unit, eliminating manual bench assembly time and potential errors.

Project-Based Inventory Management

For large-scale building management projects, KRIPAL maintains safety stock and releases shipments aligned with your commissioning schedule, rather than shipping all units at once.

Private Label & Custom Branding

Strengthen your brand with custom laser-etched labeling on the contactor face, matched to your internal part number system. KRIPAL factory branding remains discreet or is removed entirely upon request.

Engineering Application Review

Avoid field failures common with “blind” downsizing. Before finalizing your panel layout, our engineers verify your switching loads, duty cycles, and ambient temperature requirements to confirm mini contactor suitability.
