Product details

It breaks fault currents up to 4.5 kA per EN 60898 and 25 kA per IEC 60947-2, so it handles both domestic and industrial fault levels depending on the standard applied. The 2-module-width (36 mm) body fits standard DIN-rail enclosures; installation depth is 70 mm.

The 6 A rated current and C-curve mean this RCBO is sized for lighting or small resistive loads where inrush is moderate — not motor starting. The 30 mA residual provides additional protection against direct contact in final circuits. Type AC detects sinusoidal AC earth faults only; if the load includes rectifiers or VFDs that generate pulsed DC fault currents, a type A or F device would be needed. The 4.5 kA breaking capacity under EN 60898 is typical for domestic final circuits; the 25 kA rating under IEC 60947-2 confirms it can be used in industrial distribution where higher prospective fault currents exist.

Deployment context

The 2 MW (36 mm) width and 70 mm depth are the key panel-fit dimensions; verify clearance for the depth, especially in shallow enclosures. Any mounting position is allowed.

Halogen-free and silicon-free construction reduces toxic smoke and corrosive byproducts in a fire — relevant for installations in public buildings or areas with sensitive electronics.

Frequently asked questions

What is the 5SU1353-1WM06 used for?

It is a 1P+N RCBO (combined overcurrent and residual current protection) rated 6 A, 30 mA, type AC, C-curve, used in final circuits for lighting or small resistive loads in residential or commercial distribution boards.

Where can I buy the 5SU1353-1WM06?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will the 5SU1353-1WM06 drop into a panel specified for the 5SL6550-7BB?

Both are 2-module-width (36 mm) SENTRON devices with 70 mm installation depth and any mounting position, so the physical footprint is identical. However, the 5SL6550-7BB is a miniature circuit breaker (MCB) only — no residual current protection — while the 5SU1353-1WM06 is an RCBO. They are not functional equivalents; the RCBO replaces both an MCB and an RCD in one unit, so the wiring and protection scheme differ.
