Precision-Engineered for Unfailing Electrical Isolation

A reliable isolator switch is the last line of defense for maintenance safety. KRIPAL’s isolator range is built to handle high inductive loads and features a robust switching mechanism designed for thousands of duty cycles. Utilizing high-strength, UV-resistant, and flame-retardant materials, our switches maintain optimal performance even under intense sunlight or corrosive industrial fumes. With clear "ON/OFF" status indication and padlockable handles, we provide maintenance teams with the visual and physical security required to prevent accidental re-energization.

The KRIPAL Advantage: Safety, Durability, and Compliance

Universal Compatibility: Our range covers both AC Isolators for industrial machinery and DC Isolators specifically optimized for solar PV strings and energy storage systems.
IP66 Weatherproof Rating: Designed with high-performance gaskets and robust enclosures, our switches offer superior protection against dust, high-pressure water jets, and extreme weather.
Ergonomic & Secure Design: Features include padlockable handles in the “OFF” position for LOTO safety protocols and high-visibility red/yellow handles for emergency applications.
Flexible Mounting Options: Available in surface-mounted, panel-mounted, and distribution board configurations to fit any installation requirement.

Frequently Asked Questions

Explore FAQ >

What is the difference between an isolator switch and a circuit breaker?

An isolator switch is designed to provide a visible and secure physical disconnection of a circuit for maintenance safety, typically operated manually. A circuit breaker is an automatic protection device designed to interrupt current during overloads or short circuits.

Why is IP66 rating important for outdoor isolators?

An IP66 rating ensures the switch is completely protected against dust and can withstand powerful jets of water. This is critical for outdoor solar installations or industrial wash-down areas to prevent internal corrosion and electrical failure.

Are KRIPAL isolators suitable for high-voltage DC solar systems?

Yes. KRIPAL specializes in DC Isolator Switches specifically engineered for Photovoltaic (PV) applications, capable of handling voltages up to 1500V DC with rapid switching technology to safely extinguish DC arcs.

Which international standards do KRIPAL switches follow?

Our isolator switches are designed and tested according to the IEC/EN 60947-3 standard. They hold multiple global certifications, including TUV, CE, SAA, and RoHS, ensuring reliability and legal compliance worldwide.

Can your isolator switches be locked for safety during maintenance?

Absolutely. Most of our isolators feature padlockable handles in the "OFF" position. This supports Lock-Out Tag-Out (LOTO) safety procedures, ensuring the circuit cannot be accidentally switched back on while work is in progress.
