Product FAQs
6 answersWhat legacy GE circuit breaker does the ABB A2N200TW-2 replace?
The ABB A2N200TW-2 serves as a direct functional replacement for the discontinued GE THQD22200 circuit breaker. It is part of the ABB modernization of the legacy General Electric product line.
Which panelboards are compatible with the A2N200TW-2 circuit breaker?
This breaker is designed for installation in ABB ReliaGear RQ lighting panelboards. It can also be used in OEM enclosures and DIN rail applications when equipped with the proper mounting accessories.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the A2N200TW-2 features a fixed thermal-magnetic trip unit. The thermal overload protection is fixed at 200 amps, and the instantaneous magnetic short-circuit protection is fixed at 2000 amps.
Are line and load lugs included with the A2N200TW-2 breaker?
Terminal lugs are typically sold separately for the ABB Formula A2 series breakers. You must purchase the appropriate lug kits based on your specific wire gauge requirements.
Can the A2N200TW-2 be used in direct current systems?
Yes, in addition to its 240VAC rating, this breaker is rated for use in DC systems up to 250VDC. It provides a 25kA interrupting capacity for both AC and DC applications.
Does the A2N200TW-2 provide common trip protection for both poles?
Yes, this 2-pole breaker features an internal common trip mechanism. If an overload or short circuit occurs on either pole, it will simultaneously disconnect both poles to prevent single phasing and ensure system safety.
