The 63 A rating should be coordinated with:
Cable ampacity
Connected load
Installation method
Ambient temperature
Protection requirements
The RCBO also provides integrated short-circuit protection.
The specified 10 kA breaking capacity should be evaluated against the prospective fault current at the installation point.
Residual current occurs when part of the electrical current flows through an unintended path, such as leakage to earth.
The RCBO monitors the residual-current condition and disconnects the protected circuit when the specified 30 mA threshold is reached.
This adds residual-current protection to the integrated overload and short-circuit functions.
The C characteristic can be suitable for compatible loads with moderate inrush current.
Potential applications include:
Pumps
Fans
Small motors
Solenoids
Contactors
Control transformers
Industrial auxiliary equipment

The Siemens Industry Mall lists 5SU1324-7RC63 as a 63 A, 2-pole, 4-module, C-characteristic, Type A, 30 mA RCBO.
Therefore:
5SU1324-1RC63 → Type AC, 63 A, 30 mA
5SU1324-7RC63 → Type A, 63 A, 30 mA
The principal difference is the residual-current type.
The 5SU1324-7RC63 has the same basic 63 A, 2-pole, 4-module, C-characteristic and 30 mA configuration but uses Type A residual-current detection.
This makes the residual-current type an important parameter when selecting an alternative.
The Siemens 5SU1 two-pole range contains different rated-current variants.
For example, Siemens documentation lists 5SU1324 Type A C-characteristic variants at ratings including 6 A, 10 A, 13 A, 16 A, 20 A, 25 A and 32 A, depending on the exact configuration.
The 5SU1324-1RC63 is specifically the 63 A version, so its current rating must be matched with the protected circuit.
The 5SU1344 family contains 4-pole RCBOs for compatible three-phase-plus-neutral applications.
The 5SU1324-1RC63 is a 2-pole device for compatible single-phase applications.
The pole configuration must therefore be checked before selecting a replacement.
A D-characteristic Type A RCBO is intended for compatible loads with higher starting or inrush currents.
The 5SU1324-1RC63 specifically uses a C characteristic, so it should be selected where the C curve matches the load and protection-coordination requirements.
The 5SU1324-1RC63 is specifically a 30 mA configuration.
A 100 mA or 300 mA RCBO has a different residual-current operating threshold and should not be treated as an exact replacement without confirming the protection design.
The 5SU1324-1RC63 is an RCBO, not simply an RCCB.
An RCCB primarily provides residual-current protection and normally requires separate overcurrent protection.
An RCBO combines:
Residual-current protection + overload protection + short-circuit protection
in one device.
The Siemens 5SU1324-1RC63 is relevant for:
Electrical panel builders
Industrial buyers
Electrical contractors
OEMs
Machine builders
Facility-maintenance teams
Commercial electrical contractors
Electrical distributors
Automation system integrators
Electrical product dealers
