3RT1054-1AP30

The 3RT1054-1AP30 is a Siemens SIRIUS 3RT10 series S6 base contactor, rated at 115A and 55kW at 400V (AC-3). Unlike the AP36 in the same series, it does not contain auxiliary contacts. The coil is a universal 220-240V AC/DC coil, suitable for control panels with pure main circuit switching and signal switching via modules.

Siemens SIRIUS 3RT1054-1AP30 power contactor without auxiliary contacts

Product Positioning

The 3RT1054-1AP30 belongs to the Siemens SIRIUS 3RT10 large contactor series. It features an S6 frame and provides a main circuit switching capacity of 115A, 55kW/400V. The coil voltage is a universal specification of 220-240V AC/DC. The biggest difference between it and the AP36 in the same series is that the AP30 does not include auxiliary contacts at the factory. This makes it suitable for control panel designs that only require pure main circuit switching functions or where additional contact modules can be added according to actual interlocking needs.

Core Product Advantages and Features

220-240V AC/DC coil

The operating mechanism can be directly driven by 220-240V AC or DC power supply, compatible with common control power supplies in Taiwan.

The main body does not include auxiliary contacts.

The 2NO+2NC module is not included in the product specifications. External contacts can be selected separately according to actual interlocking requirements.

S6 large chassis main circuit

The AC-3 model has a rated current of 115A and a power output of up to 55kW at 400V, making it suitable for large-scale three-phase power control applications.

Dual-terminal type

The main circuit uses square terminals, while the control circuit uses screw terminals, making wiring and installation convenient.

Simplified configuration

Suitable for simplified control panels that require only master contact switching and no additional interlocking signals.

3RT1054-1AP36

The 3RT1054-1AP36 is a Siemens SIRIUS 3RT10 series S6 base contactor, rated at 115A AC-3 and 55kW at 400V. It has 2NO+2NC auxiliary contacts and a coil with a universal AC/DC voltage of 220-240V, which is a common control power supply in Taiwanese factories. It is widely used in control panels for large motors and air compressors.

3RT1054-1AM36

The 3RT1054-1AM36 is a Siemens SIRIUS 3RT10 series S6 base contactor, rated at 115A AC-3 and 55kW at 400V. It has 2NO+2NC auxiliary contacts and a coil with a universal AC/DC voltage of 200-220V, covering common medium and low voltage control power supplies. It is suitable for the start-up and shut-down control of large motors and pump systems.

3RT1054-1AF36-WH

The 3RT1054-1AF36-WH specification is comparable to the Siemens standard AF36, both featuring an S6 frame, AC-3 rated 115A, 55kW at 400V, built-in 2NO+2NC auxiliary contacts, and a coil with 110-127V AC/DC capability. The suffix "-WH" is not clearly defined in publicly available information; it is recommended to confirm the specifications before placing an order.
