Slimline interface relay 1P 6A 220…240V AC/DC IP20 SIR6WB-220-240VAC/DC-R01 865723

Compact solution for modern electrical installations

The SIR6WB narrow-profile interface relay is a professional set consisting of the socket 6WB-220-240V-U and the relay RM699BV-3011-85-1060, specifically designed for applications requiring maximum space savings while maintaining full functionality.

Construction and dimensions

The device features an exceptionally slim construction with a width of only 6.2 mm, making it an ideal solution for dense distribution boards and control cabinets. Compact dimensions of 88.6 × 6.2 × 76 mm (or alternatively 95 × 6.2 × 76.6 mm according to other sources) allow installation even in the most restricted installation spaces.

Mounting is performed on a standard 35 mm DIN rail, ensuring quick and safe installation in existing systems. The narrow-profile construction enables denser installation without compromising access to terminals or maintenance.

Electrical parameters and compatibility

The relay supports a wide supply voltage range of 220…240 V AC/DC, eliminating the need to select separate models for different power supply types. The non-polarized input (terminals A1-A2) allows connection regardless of DC voltage polarity.

The output provides one set of changeover contacts (1P) with a load capacity of:

• AC1: 6A at voltage up to 250 V
• DC1: 6A at voltage up to 30 V

The rated AC3 current is 0.186 kW, corresponding to typical low-power motor loads. Screw terminals enable secure connection of conductors with various cross-sections without risk of loosening due to vibrations or temperature changes.

Materials and durability

Contacts are made of AgSnO2 (silver-tin-oxide) alloy with a surface coated in hard gold plating. This material combination ensures:

• Excellent wear resistance during frequent switching
• Low contact resistance reducing power losses
• Resistance to corrosion and oxidation even in humid environments
• Stable operation under resistive and inductive loads

Protection class IP20 protects against finger contact and access to solid objects larger than Ø12.5 mm.

Application and functionality

The monostable switching mode of the drive ensures precise control over the load energization/de-energization moment.

The interchangeable nature of the RM699BV relay allows easy replacement without disassembling the entire socket module, significantly simplifying installation servicing and modernization. The product EAN code is 5900005241215, and ETIM class EC001437 facilitates identification in building material classification systems.

The device weighs only 30 grams, further emphasizing its compact nature while maintaining the full functionality of a professional industrial relay.
