ABB A1N100-2P Molded Case Circuit Breaker 2-Pole

ABB SACE Formula A1N100-2P molded case circuit breaker is a fixed, two-pole MCCB rated for 100 A at 240 V AC (50/60 Hz), part of ABB’s FORMULA family for low-voltage distribution. It uses a thermal-magnetic release (TMF) to provide overload protection and short-circuit protection, ensuring rapid magnetic tripping on fault currents while offering time-delayed thermal protection for sustained overloads. The device is configured with front terminals and fixed mounting, simplifying installation in panel boards and switchgear. It is UL-listed for low-voltage installations and is designed to protect feeders and branch circuits in commercial and light-industrial electrical installations where compact two-pole protection is required. With its two-pole frame, the A1N100-2P provides clear trip indication and compatibility with other FORMULA accessories, making replacement or expansion straightforward within ABB’s FORMULA lineup. This MCCB is intended for use in distribution boards, panelboards, and motor-control applications where 100 A protection at 240 V is appropriate and reliable short-circuit protection is essential.
