1SDA055009R1 ABB KIT R T4 4PCS Rear Terminal Kit

Why Choose the ABB 1SDA055009R1 KIT R T4 4PCS?

The ABB 1SDA055009R1 is a genuine rear terminal kit designed for ABB SACE Tmax T4 moulded-case circuit breakers. Identified by ABB as KIT R T4 4PCS and also known as T4 REAR TERMINAL K, the accessory provides rear-facing electrical connection points for compatible T4 circuit-breaker installations.

The kit contains four adjustable rear terminals and is intended for compatible 4-pole T4 configurations. Rear terminals are particularly useful where conductors or busbar connections need to be routed behind the circuit breaker rather than connected at the front, supporting flexible switchboard and panel layouts.

As part of ABB's Accessories for Tmax T range, the 1SDA055009R1 is engineered specifically for the T4 frame and supplied as a loose or configurable accessory. Its dedicated design makes it suitable for professional low-voltage distribution assemblies where correct mechanical compatibility with ABB SACE Tmax T equipment is essential.

Flexible Rear Connections for Tmax T4 Circuit Breakers

Rear terminals allow the main electrical connections of a moulded-case circuit breaker to be made behind the device rather than directly from its front terminals. This connection arrangement can help optimise conductor or busbar routing and is particularly useful in switchboards where front space is restricted or a rear-connected layout is preferred.

The ABB 1SDA055009R1 provides four adjustable rear terminals specifically intended for compatible four-pole Tmax T4 circuit breakers. Using a dedicated ABB connection accessory helps ensure that the terminal arrangement is appropriately matched to the circuit-breaker frame and supports orderly integration into professional low-voltage distribution assemblies.

Typical Applications

• ABB SACE Tmax T4 moulded-case circuit breaker installations.
• Four-pole low-voltage distribution systems.
• Industrial electrical switchboards.
• Power distribution panels and assemblies.
• Rear-connected circuit-breaker installations.
• Commercial and industrial electrical control panels.
