MPP2125KP - 125 Amp Circuit Breaker Description

MPP2125KP - 125 Amp Circuit Breaker

When you’re replacing a breaker in existing or legacy electrical equipment, getting the details right matters; the product designation identifies the MPP2125KP as a 125A, 4-pole, 120/240V Type MPP-PT circuit breaker with a 100K interrupt rating. It uses a thermal-magnetic trip and plug-in connection, giving you several concrete specifications to check against the breaker being replaced.

Key Features and Benefits

  • 4-pole configuration for electrical equipment designed around this specific pole arrangement.
  • 120/240V rating provides a clear reference when matching the breaker to an existing system.
  • Type MPP-PT identifies the breaker type and helps narrow down form-and-fit compatibility.
  • Thermal-magnetic trip matches the trip technology specified in the technical data.
  • Plug-in connection is an important physical compatibility point when replacing an existing breaker.
