Durability and Environmental Adaptability:

With a protection class of IP20 on the front and a degree of pollution of 3, the 3RT1016-1BB42 contactor ensures robust protection against environmental factors. Its operational altitude of up to 2,000 meters above sea level highlights its adaptability to diverse installation environments.

Temperature Resilience:

Capable of operating within a wide temperature range, from -25°C to +60°C, the contactor guarantees reliable performance in varying climates, making it suitable for a spectrum of industrial settings.

Impressive Mechanical Service Life:

Boasting an impressive mechanical service life, the contactor demonstrates a typical switching cycle of 30,000,000 for the main contacts. The addition of an auxiliary switch block extends this lifespan to 10,000,000, while compatibility with electronics-compatible auxiliary switch blocks offers a typical switching cycle of 5,000,000.

Main Circuit Features:

The 3RT1016-1BB42 contactor is equipped with three normally open (NO) contacts for main contacts, featuring an operating current of 9A at AC-3 for 400V. The inclusion of three auxiliary contacts, one normally closed (NC) and no normally open (NO) contacts, caters to instantaneous contact applications.

Robust Operating Power:

With a rated value of 13 kW at AC-1, the contactor showcases its capability to handle substantial loads. Despite this, the active power loss remains minimal at 0.7W for AC-3 at 400V, ensuring energy efficiency during operation.

Control Circuit Efficiency:

Operated by a DC voltage at 24V, the 3RT1016-1BB42 contactor displays a closing power and holding power of 3.3W each. The control circuit exhibits high reliability, experiencing only one faulty switching occurrence per 100 million cycles.

Auxiliary Circuit Specifications:

The auxiliary circuit includes one NC contact for instantaneous contact, and detailed operating currents for AC-12, AC-15, DC-12, and DC-13 provide a comprehensive understanding of the contactor's capabilities.

Short-Circuit Protection:

The contactor mandates specific fuse link designs for both auxiliary and main circuits, ensuring the safety of the electrical system in the event of a short circuit.

Efficient Installation:

Installation is facilitated by screw and snap-on mounting onto a 35mm standard mounting rail according to DIN EN 50022, and side-by-side mounting is possible.

Compact Dimensions and Versatile Connections:

The contactor's compact dimensions (45mm width, 57.5mm height, and 72mm depth) make it suitable for installations with limited space. The electrical connections, designed with screw-type terminals, accommodate various conductor cross-sections for both main and auxiliary contacts.
