Description

The Siemens SENTRON 3VM14 (630A Frame) is a robust molded case circuit breaker designed for reliable power distribution and infrastructure protection. As part of the 3VM series, it offers a cost-effective yet high-performance solution for protecting electrical installations against overloads and short circuits in industrial and commercial environments.

Key Features:

TM220 Trip Unit (ATFM): This thermal-magnetic unit features an Adjustable Thermal (Ir​) setting to fine-tune overload protection to the specific load requirements, and a Fixed Magnetic (Ii​) setting for instantaneous short-circuit protection.

Reliable Breaking Performance: With an ultimate breaking capacity (Icu​) of 55 kA, it is well-suited for main distribution boards where high fault levels may occur. The Ics​=75% rating ensures the device remains durable and operational even after clearing significant faults.

Compact Design: The 3VM14 frame is engineered to provide high amperage protection in a space-saving footprint, allowing for efficient use of space within switchgear and distribution panels.

Ease of Use: Features a clear, ergonomic handle with three distinct positions (ON, OFF, and TRIPPED) to allow for immediate status identification and rapid system recovery.

Versatile Accessories: Supports a wide range of internal accessories, including auxiliary switches, alarm contacts, and shunt trips, making it easy to integrate into remote monitoring and control systems.
