2CDE605200R0021 ABB EPDSB21 EPD-SB21 Signal Bar 21 mm

Why Choose the ABB EPDSB21 Signal Bar?

The ABB EPDSB21, type EPD-SB21, is a compact 21 mm signal bar designed for connecting the auxiliary contacts of ABB EPD24 electronic protection devices. As a dedicated accessory for the ABB EPD24 protection system, it helps simplify collective signalling connections within industrial 24 V DC control and automation installations.

ABB EPD24 electronic protection devices incorporate an auxiliary contact for status and fault signalling. The EPD-SB21 provides a convenient connection between these auxiliary contacts, reducing individual point-to-point wiring and supporting an organised power distribution and signalling arrangement within control panels.

The EPD-SB21 is supplied with grey insulation and has a length of 21 mm. Its compact format is specifically designed around the EPD24 system, whose protection devices have a module width of only 12.5 mm, making it particularly suitable for space-conscious industrial control cabinets.

Reliable Auxiliary Contact Signalling for EPD24 Systems

ABB EPD24 electronic protection devices are designed for selective protection of loads supplied from 24 V DC switch-mode power supplies. Their integrated auxiliary contacts provide status and fault information that can be incorporated into machine control, monitoring and automation circuits.

The EPD-SB21 forms part of the EPD24 connection concept, providing a dedicated signal-bar solution for auxiliary contacts while separate busbars can be used for LINE+ and 0 V distribution. This arrangement helps minimise wiring effort and creates a compact, orderly protection and signalling system within the control cabinet.

Typical Applications

• ABB EPD24 electronic protection device installations.
• Auxiliary contact signalling circuits.
• 24 V DC industrial control systems.
• PLC and machine automation panels.
• Status and fault monitoring circuits.
• Industrial control cabinets and distribution assemblies.
• OEM machinery and production equipment.
