ABB 3ABD00029943 RCM 230VAC Relay 10A 400V –40–55°C

ABB RCM 230VAC 3C/0 Relay Module 3ABD00029943

The ABB RCM 230VAC 3C/0 (3ABD00029943) is a DPDT relay module designed for industrial control applications. Featuring a 230 VAC coil and 10 A contact rating at 230 VAC, this DIN rail mounted relay provides reliable switching for motor control, lighting, and automation circuits. Weighing 0.08 kg (0.18 lbs), it offers a compact solution for panel installations.

Technical Specifications

Installation & Field Application Guide

• Mount the relay on standard 35mm DIN rail. Ensure the rail is properly grounded.
• Connect AC supply to coil terminals A1 and A2. Use 14 AWG wire rated for 230 VAC.
• Wire load circuits to the appropriate contact terminals (NO/NC). Torque terminals to 0.5-0.6 Nm.
• For inductive loads (contactors, solenoids), install an RC snubber across the contacts to suppress arcing.

Why Choose the RCM 230VAC 3C/0

• DPDT configuration provides versatile switching options for control circuits.
• 10 A contact rating handles heavy loads including motors and heaters.
• Wide operating temperature range (-40°C to +55°C) suits demanding environments.
• DIN rail mounting simplifies installation and maintenance in control panels.

Field Engineer FAQs

Q1: What is the coil power consumption of this relay?

A1: The 230 VAC coil typically consumes 0.9 VA (approx. 4 mA at 230V), making it suitable for direct PLC output driving.

Q2: Can this relay be used for DC loads?

A2: Yes, the contacts are rated for 10A at 24 VDC. However, for DC loads above 50V, derating may apply due to DC arc characteristics.

Q3: What is the expected mechanical life of the RCM relay?

A3: The relay offers >10 million mechanical operations and >100,000 electrical operations at rated load.
