HMA3800T - 800Amp Trip Unit

HMA3800T - 800Amp Trip Unit

When you're replacing a trip unit in existing electrical equipment, getting the details right matters. The HMA3800T is an 800A MARK 75 trip unit designed for compatible J-K frame molded-case circuit breaker applications. It carries a 600V rating, uses a three-pole configuration, and has a 3000–6000A magnetic trip range. Those specifications make the HMA3800T a practical choice when servicing equipment that already calls for this particular trip unit and configuration.
