Auxiliary Contact

A KRIPAL auxiliary contact block is a precision-engineered accessory that adds signaling and control capabilities to our contactors. Designed as part of a complete system of compatible accessories, it mounts seamlessly onto our contactor series. Its primary function is to provide a remote electrical signal (by opening or closing) based on the main contactor's status, enabling control logic, status indication, and system interlocking for flexible customization and future upgrades.

KRIPAL auxiliary contacts are specifically engineered for seamless integration and optimal performance with KRIPAL contactors.

This ensures:

• Guaranteed Compatibility: Perfect mechanical fit and electrical performance, eliminating the risk of misalignment or failure associated with generic brands.
• Reliable Operation: Precision engineering delivers long-term reliability, supporting the stable operation of your entire system.
• System Synergy: As part of our comprehensive accessory suite, they are designed to work flawlessly with other KRIPAL components like mechanical interlocks and surge suppressors.

KRIPAL auxiliary contact blocks are available in various configurations, including Normally Open (NO), Normally Closed (NC), and combined NO/NC modules. They are rated for lower current control circuits (typically up to 5A), making them ideal for applications such as electrical interlocking, status indication (e.g., pilot lights), and sending signals to PLCs.

Absolutely. A key feature of the KRIPAL system is its flexibility for functional expansion. Our auxiliary contact blocks are designed for simple, tool-free or easy screw-on mounting to the designated slots on our contactors. This allows for quick customization in the field without modifying the main power wiring, enabling easy upgrades based on your specific application needs.

KRIPAL provides a complete suite of accessories to enhance functionality, safety, and protection:

• Mechanical Interlocks: A hardware-based safety mechanism to prevent two contactors (e.g., in a motor reversing circuit) from operating simultaneously.
• Surge Suppression Modules: Protect your control circuit by absorbing voltage spikes generated during contactor switching, increasing component lifespan and reducing electromagnetic interference (EMI).
• Timing Delay Attachments: Add time-delay functions for advanced control sequences.

KRIPAL auxiliary contacts are versatile and essential for:

• Electrical Interlocking: Creating safety and operational sequences between multiple devices.
• Status Indication: Providing remote signals to control panels or HMIs to indicate if a contactor is energised or de-energised.
• Control Logic Expansion: Serving as an input for Programmable Logic Controllers (PLCs) or other control systems to automate complex processes.

If you suspect a fault, please:

1. Disconnect all power to the contactor and control circuit for safety.
2. Verify the model is compatible with your specific KRIPAL contactor series.
3. Check the mounting to ensure it is properly seated and aligned on the contactor.
4. Inspect the wiring to the block's terminals for secure and correct connections.
5. Test the contact with a multimeter for continuity in both the energised and de-energised states of the contactor.
