For compliance documentation: as a Siemens SENTRON product, it is designed to meet IEC/EN 61008-1 (RCCB standard) and carries CE marking for the European market. The evidence also lists conformity to DIN EN 61346-2 and DIN EN 81346-2 functional designations (F for protective device). RoHS and REACH declarations are standard Siemens documentation available on request. The 40 A rated current (In) and 100 mA residual trip (IΔn) define the protection envelope: the RCCB will carry 40 A continuously in a 30 °C ambient, and it trips when leakage to earth exceeds 100 mA. The 100 mA threshold is typical for sub-distribution boards or circuits where a 30 mA device would nuisance-trip due to natural cable leakage — think long runs to outbuildings, industrial socket circuits, or fixed equipment with some standing leakage. The instantaneous design (no short-time delay) means it responds within milliseconds to fault currents, which is the standard for general-purpose shock protection in most IEC markets. Terminals accept solid or stranded conductors from 1 to 16 mm² (roughly 18 AWG to 6 AWG), with a tightening torque of 2.5 to 3 N·m. The IP20 rating is standard for enclosed distribution boards — the device itself is finger-safe (finger and back-of-hand safe per the evidence), but it needs the cabinet door closed to maintain the IP rating. The 36 mm width (2 modular units per DIN 43880 size 1) means it occupies two standard 18 mm slots in the distribution board.","metaTitle":"Siemens 5SM3414-6KL SENTRON RCCB, 2-pole, 40 A, 100 mA, 230","metaDescription":"Siemens 5SM3414-6KL SENTRON RCCB, 2-pole, Type A, 40 A rated, 100 mA trip, 230 V AC, 10 kA SCCR.

The 5SM3414-6KL is a residual current device that detects earth faults; the 5SL6550-7BB provides overcurrent and short-circuit protection only. They serve different protection functions and are not drop-in substitutes — a panel specified around one cannot simply swap for the other without redesigning the protection scheme."},{"question":"What is 5SM3414-6KL's listed depth?","answer":"The device depth is 70 mm, which matches the installation depth on the DIN rail. This is a standard depth for SENTRON modular devices and fits most enclosed distribution boards."},{"question":"What conductor sizes does the 5SM3414-6KL accept?","answer":"The screw-type terminals accept solid or stranded conductors from 1 to 16 mm² (approximately 18 AWG to 6 AWG).
