Detailed Description

Product Overview
The ABB 1SDA101368R1 is a high-capacity molded-case circuit breaker (MCCB) from the Tmax XT7S M family. This model is rated for 1250 A, is configured as 3-pole (3p) with fixed mounting and front-terminal connection (designation “F F”), and features the EKIP DIP LS/I solid-state electronic trip unit — offering advanced protection and monitoring in industrial power-distribution applications. 

Key Specifications

• Rated current (Iₙ): 1250 A 

• Poles: 3-pole (3p) 

• Trip unit: EKIP DIP LS/I (electronic solid-state release)

• Weight: ~14.758 kg 

• Standards: Complies with IEC 60947-2 (low-voltage switchgear & circuit-breakers) 

Features & Benefits

• High capacity: With 1250 A rating and robust short-circuit performance (50 kA @ 415 V, 85 kA @ 220-240 V), this breaker supports heavy duty applications.

• Electronic trip unit (EKIP DIP LS/I): Offers adjustable long-time, short-time, instantaneous protection as well as diagnostic capabilities — which enhances selectivity and protection coverage versus traditional thermal-magnetic breakers.

• Compact footprint: Despite high ratings, the physical dimensions are moderate, aiding integration into panels and switchgear.

• Front-terminal fixed mounting: Simplifies installation in switchboards and allows easier access for wiring and maintenance.

• Sustainable design: As part of ABB’s product line, likely aligns with EcoDesign and recyclability initiatives (though confirm via datasheet).

• Industrial-grade reliability: Designed for demanding environments — high current, frequent operations, fault interruption — with tested mechanical and electrical endurance.

Applications / Use Cases

• Protection of main feeders, sub-distribution boards in large industrial plants

• Generator or transformer secondary protection circuits

• Distribution in commercial buildings, data centres, hospitals where high current ratings and selectivity are needed

• Upgrades or replacements in switchgear requiring modern electronic trip units and front-access wiring layout
