The Siemens SENTRON 3VA2116-5HL36-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous current of 160 A across ambient temperatures up to 50 °C, with a 154 A rating at 55 °C and 136 A at 70 °C. It carries an interrupting capacity of 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V — figures that govern its fault-clearing capability at the point of installation. The ETU320 electronic trip unit provides line protection with adjustable settings, and the breaker ships with two auxiliary switches (HP type) for status feedback to a PLC or annunciator panel. No undervoltage release, no voltage trigger, no communication module, and no ground-fault monitoring are fitted on this variant — the base configuration is a straightforward thermal-magnetic replacement with electronic trip logic.
Panel fit and mounting
The 3VA2116-5HL36-0AB0 measures 105 mm wide by 181 mm high by 86 mm deep, fitting standard SENTRON 3VA panel cutouts and busbar systems. Front-side IP40 protection means it is suitable for enclosed distribution boards where splash or tool ingress is not a concern; no washdown rating is claimed. Maximum power loss is 25.5 W, which should be factored into enclosure thermal calculations if the breaker is densely grouped. The latching endurance of 20 000 operations aligns with typical MCCB service life for feeder and main-switch duty in industrial panels.
