It's designed as a reversing starter per, meaning it contains two contactors mechanically interlocked to prevent both directions being energized simultaneously, plus a bimetal overload relay adjustable from 2.8 to 4 A. The 4 A AC-3 rating tells you it's sized for standard squirrel-cage induction motors — the 1.5 kW power figure is the real-world motor you'd hang off it. ## Integration and wiring — what connects where Main power comes in through an ISO23570 socket, and the load side feeds out through another ISO23570 socket — this is a standardized industrial connector interface, not screw terminals. The main current circuit uses tab terminals for the motor connections. Control supply voltage is 24 V DC nominal, with a tolerance range of 20.4 to 28.8 V. Communication and supply voltage for the electronics ride the backplane bus — so this unit is designed to sit in a SIRIUS modular system, daisy-chaining power and PROFIBUS DP to neighboring modules. No digital I/O on board; all control signals come through the bus. Dimensions are 270 mm high, 140 mm wide, 134 mm deep — factor that into your gland plate layout and enclosure depth. ## Protection and motor brake Short-circuit protection is handled by upstream circuit-breakers, not fuses — the starter itself doesn't contain the short-circuit device; you coordinate a breaker ahead of it. The overload relay is bimetal type, thermal, adjustable. A motor brake output is integrated — if your application uses a holding brake, this module can switch it directly, saving an external contactor. The unit carries three poles for the main current circuit.","metaTitle":"Siemens 3RK1300-1ES01-1AA4 Reversing Starter, 4A AC-3, 1.5 k","metaDescription":"Siemens 3RK1300-1ES01-1AA4 reversing starter, rated 4A AC-3 at 400V for 1.5 kW motors.
