GENERAL ELECTRIC TQDL21200 Plug In Circuit Breaker Tqdl 200 Amp 240vac 2p 10kaic@120v

General Electric TQDL21200 plug-in circuit breaker is designed to protect against faulty currents in panelboards and switchboards.

Working Mechanism:

• The circuit breaker opens when pressure is applied to the trigger.
• When faulty current flows through the system, the trip coil of the breaker gets activated.
• This moves the contacts away from each other and opens the circuit.

Features:

• It provides 200A standard current rating with a maximum interrupting capacity of 10kAIC at 120V.
• This circuit breaker features a thermal-magnetic trip unit, providing long-time and instantaneous current limiting functions.
• It is equipped with load-side lug terminals for connecting multiple sections of the panelboard.

Standards and Approvals:

• UL

Frequently Asked Questions:

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 is the maximum operating temperature of this General Electric TQDL21200 plug-in circuit breaker?

A. It can be operated at temperatures up to 75 degrees C.

Q. What factors should be considered while choosing an MCCB?

A. Major factors include current & voltage ratings, frame size and ultimate short-circuit breaking capacity.
