TPM1-63-125-250-320-400-630-800-1250-1600L/M Molded Case Circuit Breaker for AC Systems
Professional AC MCCB solutions for commercial and industrial electrical systems/Standard: IEC 60947-2
This molded case circuit breaker is designed for higher-current AC distribution systems in buildings, industrial facilities, and infrastructure projects. It provides overload and short circuit protection for feeders, large loads, and main incoming circuits where stronger protection capacity is needed. With wider current options, durable breaker structure, and support for low-voltage distribution applications, it helps improve protection reliability and power control.
General
TPM1 series moulded case circuit breaker (MCCB) is developed with advanced design concepts and proven manufacturing processes. According to the rated ultimate short-circuit breaking capacity (Icu), it is available in L type (standard) and M type (high breaking) versions. Featuring a compact structure, high breaking performance, short arc distance and good vibration resistance, TPM1 is suitable for both onshore and marine power distribution applications.
TPM1 is used in AC 50Hz distribution networks with rated insulation voltage up to 800V (frame 63: up to 500V), rated operational voltage up to 690V (frame 63: up to 400V), and rated current up to 1600A. It is designed for power distribution and for protecting lines and electrical equipment against overload, short circuit, and undervoltage. For motor circuits, it supports infrequent starting and provides protection against overload, short circuit, and loss/undervoltage.
For the 63–630A three-pole models, a transparent front cover option is available, allowing easier visual inspection of operating status. The breaker can be installed vertically or horizontally.
Standard: IEC 60947-2.

Curve of TPM1 Molded Case Circuit Breaker
Operating conditions
- Temperature: -5°C~+40°C; the average value within 24h shall not exceed +35°C. For the circuit breaker with
thermo-magnetic release, +40°Cis set to be the standard temperature for ratings. For temperature not between
-5°C~+40°C, please contact us for temperature compensation
correction;
- Altitude: not exceed 2000m (Please contact with us for reduction coefficient if altitude at the mounted site exceed
2000m)
- Pollution grade: Grade 3;
- Air conditions:At mounting site, relative humidity not exceed 50% at the max temperature of +40°C, higher
relative humidity is allowable under lower temperature. For example, RH could be 90% at +20°C. Special measures
should be taken when dew occurs.
