Siemens 3VA1096-4ED32-0AC0 – 16 A SENTRON MCCB for Line Protection
The Siemens 3VA1096-4ED32-0AC0 is a 3-pole SENTRON molded case circuit breaker (MCCB) designed for line protection, carrying a continuous rated current of 16 A up to 55 °C before derating begins at 60 °C. Its interrupting capacity hits 121 kA at 240 V, dropping to 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V — numbers that tell you this breaker handles high-fault scenarios at lower voltages without cascading upstream. The TM210 thermal-magnetic overcurrent release provides fixed thermal and magnetic trip settings, and the breaker ships with two HQ auxiliary switches for status feedback to a PLC or annunciator panel.
Panel Fit – Dimensions and Integration
At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard DIN-rail or panel-mount layouts. Rated insulation voltage is 800 V, with an operating temperature range from -25 °C to 70 °C.
Key Ratings – What They Mean for Your Application
The 16 A rating holds steady through 55 °C ambient; at 60 °C it derates to 15 A, and at 70 °C it still carries 15 A — useful if the panel sits near a heat source or in a non-conditioned space. With 121 kA breaking capacity at 240 V, this MCCB can be applied on the secondary side of a 150 kVA transformer feeding a high-fault distribution board, provided the available fault current stays under that number. The 3-pole design with no undervoltage release or ground-fault monitoring keeps it straightforward for straight line protection — no extra coils to fail or nuisance trips to chase.
