Product Positioning

The 3RT2016-2AP04-3MA0 is a model in the SIRIUS 3RT2016 series with a control coil designed for 230V AC (50/60Hz). It is suitable for applications where there is already a 220~230V single-phase power supply but no additional 24V control transformer is desired. The coil can be directly driven by the factory's power distribution system. The main contacts maintain the standard S00 frame specifications of AC-3 9A, 4kW/400V, and the AC-1 rated current can reach 22A. The auxiliary contacts are factory-configured with 2 sets of normally open and 2 sets of normally closed contacts, and the terminals are spring clip type for easy wiring and maintenance replacement.

Core Product Advantages and Features

230V AC coil without the need for a control transformer

The coil directly corresponds to a 220~230V single-phase power supply, saving the cost and wiring space of configuring an additional 24V control transformer.

AC-3 9A/4kW main contacts

The main circuit specifications are the same as the 3RT2016 series, with a rated current of 9A and 4kW at 400V. The AC-1 can reach 22A, which is suitable for general pump and fan loads.

2NO+2NC auxiliary contact group

Four auxiliary contacts are fixedly installed at the factory, making it convenient to obtain both operation indication and interlock protection signals at the same time.

Spring-loaded terminals, lightweight design

The main control circuits all feature spring clip terminals, eliminating the need for screwless wiring; the actual net weight is approximately 0.31 kg, maintaining the same size as the S00 frame.
