Siemens 3RT1 Series Contactor, 150A Operational Current, 400V Control Circuit Voltage Uc - 3RT1055-6LA06

This contactor is a three-pole industrial switching device designed to control and protect AC motors and heavy loads in automated systems. It is intended for DIN-rail or screw-fixing installations and incorporates instantaneous auxiliary contacts to support control and signalling circuits in electrical distribution and motor starter assemblies.

Features & Benefits

• Rated operational current 150A for heavy-duty switching
• Power handling 75kW at 400V for motor load capacity
• Three main poles with three normally open contacts for load separation
• Auxiliary configuration 2NO/2NC to expand control functions
• Screw terminals for auxiliary and control ease of wiring
• Suitable for protective separation of Coil and main contacts up to 690V

Applications

• Suitable for 3-phase motor starters in industrial plants
• Ideal for switching heavy-duty AC-3 motor loads at 400V
• used with control panels requiring auxiliary signalling contacts
• can be used in automation racks with DIN-rail mounting
• Suitable for retrofit installations using connection bars

What types of connection methods does it provide for the main circuit?

The main circuit uses a connection bar arrangement designed for large cross-sections and high current-carrying capacity.

What ambient conditions can it operate under?

It functions between -25°C and +60°C and is rated for installation altitudes up to 2000 m with relative humidity up to 95% at 55°C.

How does it perform under frequent switching demands?

Mechanical endurance is specified at around 10,000,000 operating cycles, and no-load switching frequency is up to 2000 operations per hour.

What short-time withstand capability is available for cold starts?

Short-time current capacity includes limits such as 2727A for 1 s and 703A for 60 s at 40°C cold operating state.

What protective spacing or mounting clearance is required when installed side-by-side?

Side-by-side mounting requires 0mm lateral clearance with forward spacing of 20mm and vertical spacing of 10 mm.
