Product Identification and Core Ratings
The Siemens SENTRON 3VA1132-4EF36-0AH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection applications, fitted with a TM240 thermal-magnetic overcurrent release. Per the specification, it carries a rated current of 32 A across the ambient temperature range from 40 °C to 50 °C, derating to 30 A at 70 °C — a curve that must be consulted for panel fill factor and enclosure thermal rise calculations. Breaking capacity is voltage-dependent: 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at both 500 VAC and 690 VAC. The rated insulation voltage is 800 V. These figures govern selectivity coordination with upstream devices and SCCR compliance for the panel assembly.
Physical Integration and Auxiliary Configuration
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard SENTRON 3VA frame size that mounts on a DIN rail or panel-mount adapter within the enclosure. The unit ships with a basic switch (order code 3VA11324EF360AA0) and is pre-configured with 2 auxiliary switches plus 1 trip alarm switch (HQ type), eliminating the need for separate add-on modules in most line-protection schemes. Maximum power loss is 10.6 W. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The trip indicator is present; undervoltage release and ground-fault monitoring are not fitted on this variant.
