Common Questions

What is the main advantage of a resettable circuit breaker over a fuse?

A resettable circuit breaker, like this 180A unit, can be manually reset after an over-current event, eliminating the need to replace blown fuses. This offers greater convenience and reduces ongoing costs.

Can this circuit breaker be used as a simple on/off switch?

Yes, this circuit breaker features a manual-break option, allowing it to function as an isolator on/off switch for easy disconnection and reconnection of your DC system.

What does the IP67 rating mean for this product?

An IP67 rating indicates that the circuit breaker is fully protected against dust ingress and can withstand temporary immersion in water up to 1 metre deep for a specified duration. This makes it suitable for outdoor or marine environments.

Is this circuit breaker suitable for high-temperature applications?

Yes, it is constructed from UL 94V-0 rated thermal plastic, engineered to withstand high temperatures and exhibit excellent flame retardancy, ensuring reliable operation in demanding conditions.

Installation Notes

  • This circuit breaker is designed for surface mounting. Ensure a flat, stable surface for secure installation.
  • Always disconnect power before installation or maintenance to prevent electrical shock.
  • Ensure correct polarity when connecting DC wiring to the M6 terminals.
