Masterpact MTZ devices are designed for specified operating conditions in terms of temperature, humidity, vibration, altitude, corrosion, and electromagnetic disturbances.
Beyond the limits defined here, the circuit breakers suffer accelerated aging that may rapidly result in equipment breakdowns.
Refer to the Masterpact Maintenance Guide for additional information and consult Schneider Electric to confirm mechanical and electrical performances in severe conditions.
Examples of applications with severe operating conditions:
power frequency converters installed in the same electrical equipment or close to the Masterpact circuit breaker
high vibration marine applications such as thrusters and anchor positioning systems
