ABB / General Electric TEY220 Miniature Circuit Breaker

General Electric's industrial solutions division was acquired by ABB [1.1.2]. Depending on the exact production date, this breaker may arrive with either GE or ABB branding on the label, but the TEY220 catalog number, internal components, and physical dimensions remain identical.

The TEY220 is designed specifically for GE A-Series lighting panelboards. It is commonly installed as a branch circuit breaker in AE and AD type panels operating on 480Y/277VAC or 240VAC systems.

No. While both feature a 1-inch per pole width and a bolt-on design, they are built for different GE panelboard lines. THQB breakers are used in AL and AQ series panels rated up to 240VAC, whereas TEY breakers are required for AE and AD series panels rated for 480Y/277VAC.

Yes, the TEY220 is HACR rated, making it fully certified for heating, air conditioning, and refrigeration equipment branch circuit protection. It is also HID rated for managing the inrush currents of high-intensity discharge lighting circuits.

Yes, this thermal-magnetic breaker is rated for DC applications. It provides an interrupting capacity of 10kA at 250VDC, which is frequently required for industrial control panels, automation equipment, or battery-fed systems.

No, it features a fixed thermal-magnetic trip unit. Both the long-time (L) overload and instantaneous (I) short-circuit trip functions are factory set and non-interchangeable.

The breaker utilizes a bolt-on mounting base that secures directly to the interior bus of an A-Series panelboard. The load side features mechanical lugs that accept 14-10 AWG copper or 12-10 AWG aluminum wiring.

Yes, the breaker includes an easy-to-spot visual trip mechanism. When a fault or overload occurs, the toggle handle automatically drops to a center position, clearly showing electricians which circuit requires attention before safely restoring power.
