ABB 1SAR533141R0003 – C574 Safety Relay (Legacy Spare, Replaced by Jokab RT7B)
The ABB 1SAR533141R0003 is a C574 safety relay from ABB’s former C57x safety relay range, used in machine safety circuits to monitor safety devices and safely disconnect hazardous motion. ABB has discontinued the C57x series and replaced it with safety relays from its Jokab Safety range. Atlantech Drives helps you keep existing machines running by sourcing the original C574 where available, and by guiding you to the official ABB replacement when an upgrade is the better option.

Replacing the C574 with the ABB Jokab RT7B
According to ABB’s safety relay conversion table, the official replacement for the 1SAR533141R0003 is the ABB Jokab RT7B (2TLA010028R1000). Before switching, note this important difference:
| C574 (1SAR533141R0003) | RT7B (2TLA010028R1000) | |
|---|---|---|
| Switching capacity AC15, 240 V AC | 5 A | 2 A |
| Switching capacity DC13, 24 V DC | 5 A | 1 A |
If the safety outputs of the C574 switch loads above the RT7B ratings, the circuit must be reviewed (for example, by adding contactors) before replacement. Any change to a safety circuit must be validated by the machine builder or a qualified safety engineer.
