1SDA105123R1 ABB MIR-P XT5 P/W 400A FP Mechanical Interlock Plate

Why Choose the ABB 1SDA105123R1 MIR-P XT5 P/W 400A Mechanical Interlock Plate?

The ABB 1SDA105123R1, designated MIR-P x XT5 P/W 400A FP, is a mechanical interlock mounting plate for ABB SACE Tmax XT5 plug-in and withdrawable circuit breakers. Specifically designed for the XT5 400 A platform with fixed part, it provides the dedicated breaker-side interface required when incorporating the circuit breaker into a compatible ABB mechanical interlocking system.

Mechanical interlocking provides a physical means of coordinating circuit breaker operation and preventing operating combinations that are not permitted by the electrical system design. The MIR-P plate is used with ABB's mechanical interlock arrangement to support applications such as source changeover, supply interlocking and industrial power distribution systems.

As a genuine ABB SACE Tmax XT mechanical accessory, the 1SDA105123R1 is engineered for XT5 400 A plug-in and withdrawable circuit breakers with fixed part. It measures 200 × 10 × 250 mm (W × H × D), has a net weight of approximately 2.7 kg and is designed in accordance with IEC 60947-2 requirements.

Reliable Mechanical Interlocking for XT5 Power Distribution

Mechanical interlocking provides a physical method of coordinating the operating states of circuit breakers. In applications involving alternative supplies or changeover arrangements, an interlock can prevent incompatible breakers from being closed simultaneously, helping the switchboard operate according to its intended electrical sequence.

The ABB 1SDA105123R1 provides the dedicated MIR-P plate for an XT5 400 A plug-in or withdrawable circuit breaker with fixed part. When combined with the appropriate ABB interlock chassis and associated components, it enables the breaker to form part of a robust mechanical interlocking arrangement for professional low-voltage distribution systems.

Typical Applications

• ABB SACE Tmax XT5 400 A circuit breaker installations.
• XT5 plug-in and withdrawable circuit breaker configurations.
• Mechanical circuit breaker interlocking systems.
• Electrical source changeover arrangements.
• Industrial low-voltage switchboards.
• Power distribution systems requiring mechanically coordinated breaker operation.
