About Siemens SIRIUS 3RV2 Motor Protection Circuit Breaker 16A
Siemens Sirius 3RV2 Motor Protection Circuit Breaker 16A — Short Circuit and Overload Protection
The Siemens Sirius 3RV2 motor protection circuit breaker combines short circuit protection (50kA) and motor overload protection in a compact 45mm width — the standard solution for motor feeders in Saudi industrial control panels. The 3RV2 eliminates the need for separate fuses + thermal relay combinations, reducing panel space and installation cost.
Key Features
50kA Short Circuit Rating: Full short circuit protection without upstream fuse — suitable for TN-S and TN-C-S systems common in Saudi industrial facilities.
Adjustable Thermal: Dial-adjustable overload setting from 10A to 16A — covers 4kW to 7.5kW motors at 400V.
Padlockable OFF: Lockout-tagout compliance required at Saudi Aramco sites — padlock in OFF position prevents re-energization.
