Cutler-Hammer FS220100A 2-Pole Circuit Breaker

Cutler-Hammer FS220100A is a 2-pole circuit breaker rated for 100 amps at 240 volts, designed for bolt-on mounting in compatible electrical panels. By interrupting both poles on a 240V circuit when the current exceeds the 100 A rating, it provides overcurrent protection that helps prevent wiring damage and fire hazards in electrical systems. The 2-pole design ensures simultaneous disconnection of both live conductors in a 240V circuit, which is important for safely interrupting power to dual-leg loads. The FS220100A is intended for use wherever a reliable 2-pole, 100A device is required to protect 240V circuits, with a bolt-on mounting configuration for secure panel attachment. Model FS220100A identifies this specific breaker within the Cutler-Hammer product line. Bolt-on mounting typically provides a secure mechanical connection to the panel, helping maintain contact and stability in installations. Bolt-on mounting provides a rigid fixed connection to the panel, which helps resist vibration and movement in standard electrical enclosures.
