EATON GHB3050 Molded Case Circuit Breaker, Type Ghb, 3-Pole, 50 A, 480Y/277 Vac, 125/250 Vdc

Eaton GHB3050 C Series moulded case circuit breaker provides overload protection and switching in AC & DC systems.

Working Mechanism:

• The circuit breaker is opened when pressure is applied to the trigger.
• When faulty current flows through any part of the system, the trip coil of the breaker gets activated, thus moving away from each other and opening the circuit.

Features:

• This circuit breaker features 3-pole, 3-phase configuration for high-speed blow open action.
• It is equipped with bolt-on load side lug terminals for secure connection.
• This circuit breaker has a 50A standard current rating and a maximum interrupting capacity of 14kAIC.
• It features a non-interchangeable thermal-magnetic trip unit offering both long-time and instantaneous current limiting functions.

Compatible Accessories:

• Pow-R-Line 1a Lighting Panelboards: They provide a flexible and compact solution for electric power distribution, along with surge protection. These panelboards meet NEMA PB1 and UL 67 standards for use in data centres and healthcare facilities.

Standards and Approvals:

• UL
• CSA

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.
