Instantaneous tripping characteristic, no short-time delay. This is the part that sits downstream of the main breaker to protect against earth faults in single-phase AC circuits. Above 45 °C the derating curve kicks in: 60.48 A at 50 °C, stepping down to 50.4 A at 70 °C (–). The 300 mA residual trip is an equipment-protection level, not personnel protection (that's 30 mA); it's sized to catch insulation degradation on motor feeders or distribution subcircuits before it escalates. Not suitable for pulsating DC or smooth DC faults — those require type A or type B RCCBs. For standard single-phase lighting, heating, and motor circuits with no rectifiers or VFDs downstream, type AC is the common choice. Snap-on DIN rail (REG) mount, 2 module width units, 55 mm installation depth. Mounting position any — horizontal or vertical orientation doesn't affect the trip mechanism. Supply connection from top or bottom. IP20 with conductors connected and distribution board installed — it's an enclosed-panel part, not for open wet locations. Finger and back-of-hand safe touch protection — the terminals are shrouded to IP20 touch-safe standards once wired. Silicon-free construction relevant for potting or conformal-coating environments where silicone outgassing can cause contact contamination.","metaTitle":"Siemens 5SM1616-0 SENTRON RCCB, 63A 300mA 2-Pole AC Type","metaDescription":"Siemens 5SM1616-0 SENTRON RCCB, 63A rated, 300mA trip, 2-pole AC type, 230V.

The 5SM1616-0 is a 2-pole RCCB (residual current protection only). The 5SL6563-7BB is a miniature circuit breaker (overcurrent protection only). They are not drop-in substitutes — a panel specified around the 5SL6563-7BB would need a separate RCCB or an RCBO to get earth-fault protection. The 5SM1616-0 occupies the same DIN footprint (2 MW) and can share the same distribution board."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SM1616-0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SM1616-0 when reusing this data.
