Why Choose the ABB 1SDA100329R1 Ekip Touch Measuring LSIG Trip Unit?
The ABB 1SDA100329R1 is an Ekip Touch Measuring LSIG electronic trip unit designed for compatible ABB Tmax XT4 4-pole moulded case circuit breakers. Rated at 250 A, it combines configurable electronic circuit protection with integrated measurement capabilities for modern AC low-voltage power distribution systems.
Its LSIG protection functions provide long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. The Ekip Touch Measuring platform also provides measurement capability and is prepared for communication, making it suitable for installations where circuit protection, electrical monitoring and connectivity are required within the same circuit-breaker architecture.
The 1SDA100329R1 is supplied as a loose or configurable 4-pole electronic release and must be combined with a compatible ABB Tmax XT4 breaking part to form a complete circuit breaker. Its overload protection is adjustable from 0.4–1 × In, while short-circuit protection is adjustable from 1–10 × In with time-delay capability, supporting coordinated protection of feeders and connected equipment.
