1SDA073877R1 ABB PB Separators H=100mm 4pcs E1.2 F 3P

Why Choose the ABB PB Separators H=100mm 4pcs E1.2 F 3P?

The ABB PB Separators H=100mm 4pcs E1.2 F 3P, order code 1SDA073877R1, are a set of four insulating phase separators designed for three-pole fixed ABB SACE Emax 2 E1.2 air circuit breakers. Each separator has a height of 100 mm and is installed at the breaker terminal area to provide additional physical separation between adjacent phases.

ABB PB separators are insulating barriers that fit into dedicated provisions at the rear of compatible circuit breakers. By increasing physical segregation between the terminal areas of neighbouring poles, they support orderly terminal separation and insulation coordination within low-voltage switchgear assemblies.

The 1SDA073877R1 kit contains four plastic separators and is specifically configured for fixed, three-pole E1.2 installations. The accessory is also associated with compatible ABB Emax 3 E1.3, Tmax XT7 and XT7M platforms, providing switchboard builders with a genuine ABB phase-separation solution for compatible fixed circuit-breaker arrangements.

Reliable Phase Separation for Fixed Emax 2 Breakers

The terminal area of a high-current air circuit breaker contains conductors belonging to separate electrical phases in relatively close proximity. ABB PB separators provide dedicated insulating barriers between these phase areas, increasing physical segregation around the circuit-breaker connections and supporting an organised switchgear installation.

For the E1.2 fixed three-pole configuration, the 1SDA073877R1 provides four 100 mm-high barriers engineered for the compatible breaker arrangement. Using the specified ABB accessory helps ensure that the separator geometry and installation interface correspond with the circuit-breaker design rather than relying on generic fabricated barriers.

Typical Applications

• ABB SACE Emax 2 E1.2 fixed three-pole air circuit breakers.
• Phase separation around circuit-breaker terminal connections.
• Industrial low-voltage distribution switchboards.
• Power-distribution and motor-control assemblies.
• Generator and critical-power switchgear.
• Infrastructure, utility and process-industry electrical panels.
