Alstom MVAJ11D1GB0771A Low Burden Tripping Relay

Alstom MVAJ11D1GB0771A Low Burden Tripping Relay is a member of the MVAJ11–34 family of fast-acting trip relays used to initiate circuit-breaker tripping in protection schemes, offering a low-burden coil option to minimize control-current draw. The MVAJ11 series includes low-burden variants that provide high-speed operation and compliance with ESI 48-4 Class EB1, making them suitable for critical trip paths where rapid interruption is required. This specific unit is described as brand-new in a bag, with model designation MVAJ11D1GB0771A, intended for use as a tripping relay within established protection architectures—typically coordinating with other trip and interposing equipment in substation or industrial protection schemes. In practical terms, the MVAJ11 low-burden relay is employed where a dedicated tripping signal must actuate a circuit breaker quickly, while keeping the burden on the control circuit to a minimum, enabling reliable protection without excessive control-current draw.
