1SDA060314R1 ABB T6L 800 Ekip M-LRIU In=630 3p F F Motor Protection MCCB

Why Choose the ABB T6L 800 Ekip M-LRIU In=630 3p F F?

The ABB 1SDA060314R1 is a genuine SACE Tmax T6L moulded case circuit breaker for motor protection. Identified in current ABB documentation as T6L 800 Ekip M-LRIU In=630 3p F F, and also associated with the earlier PR222MP-LRIU designation, it combines a T6L 800 frame with a 630 A electronic release, three-pole construction, fixed installation and front terminals.

The integrated Ekip M-LRIU electronic trip unit is specifically designed for motor applications and provides multiple protection functions. These include overload protection (L), locked-rotor protection (R), instantaneous short-circuit protection (I) and phase-unbalance protection (U). The overload threshold is adjustable from 0.4–1 × In, while the instantaneous magnetic threshold is adjustable from 6–13 × In.

The T6L performance level provides high short-circuit interruption capability, including an ultimate short-circuit breaking capacity of 100 kA at 380/400/415 V AC. With its 630 A release rating, motor-specific electronic protection and fixed three-pole construction, the ABB 1SDA060314R1 is suited to demanding industrial motor feeders, process equipment and motor control applications.

LRIU Electronic Protection for Industrial Motors

Motor circuits have protection requirements that differ from conventional distribution feeders because high starting currents must be distinguished from genuine overload, locked-rotor and short-circuit conditions. The Ekip M-LRIU release fitted to the ABB 1SDA060314R1 provides dedicated protection functions for these conditions, combining overload, locked-rotor, instantaneous short-circuit and phase-unbalance monitoring in a single electronic trip unit.

The release has a nominal current of 630 A, with overload adjustment from 0.4–1 × In, locked-rotor protection adjustable from 3–9 × In and instantaneous short-circuit protection adjustable from 6–13 × In. Combined with the T6L platform's 100 kA breaking capacity at 380/400/415 V AC, this provides robust protection for large industrial motors and associated feeder circuits.

Typical Applications

• Large industrial motor feeders.
• Motor control centres and industrial switchboards.
• Pumps, fans and compressor systems.
• Conveyors and materials-handling equipment.
• Industrial process machinery.
• HVAC and building-services motor circuits.
• Motor circuits requiring phase-unbalance protection.
• Installations with high prospective short-circuit currents.
