ABB 1SAM250000R1005 MS116-1.0 is a three-pole manual motor starter with an adjustable 0.63–1.00 A thermal range, Class 10A tripping and integrated overload, short-circuit and phase-failure protection.
£77.06
The ABB 1SAM250000R1005, also designated the MS116-1.0, is a compact and reliable manual motor starter and motor protection circuit breaker designed for switching and protecting three-phase motors. It combines manual control, disconnection, thermal overload protection and electromagnetic short-circuit protection within a single 45 mm-wide device.
The adjustable thermal release covers motor currents from 0.63 to 1.00 A, allowing the protection setting to be matched precisely to the motor’s rated current. Phase-failure sensitivity and a Class 10A tripping characteristic provide dependable protection against sustained overloads and abnormal three-phase operating conditions.
With a rated motor power of 0.25 kW at 400 V AC and a rated service short-circuit breaking capacity of 50 kA at 400 V AC, the MS116-1.0 is suitable for small industrial motors used in pumps, fans, conveyors and machinery. Its rotary handle provides clear manual operation, while the compact DIN rail-mounted format simplifies control-panel installation.
Manual motor starters such as the ABB MS116 protect motors using thermal and electromagnetic release mechanisms. The adjustable thermal release responds to sustained overloads, while the electromagnetic release rapidly disconnects the circuit when a high short-circuit current occurs.
The MS116-1.0 can be used independently for local motor switching or combined with a compatible contactor to create a remotely controlled motor starter. Auxiliary contacts, signalling contacts, voltage releases, busbars and protective enclosures can also be added to meet different control and installation requirements.
