Frequently Asked Questions:

Q. What is the maximum operating temperature of Eaton GHB3050 moulded case circuit breaker?

A. This circuit breaker can be operated at temperatures up to 158 degrees F.

Q. Which type of terminal connection is used in this circuit breaker?

A. This circuit breaker uses a screw clamp connection for added safety.

Q. What is the difference between MCCBs and MCBs?

A.

• MCBs protect items from current overloads while MCCBs protect equipment from fault currents & excess temperature rise.
• The tripping circuit of MCBs is fixed while MCCBs have a movable tripping circuit.
• MCBs have comparatively low interrupting ratings than MCCBs.

Q. What causes moulded case circuit breakers to trip?

A. Overloading a circuit is the primary reason for frequent short-circuit tripping.
