This makes it a better fit for modern panels than a basic Type AC device. The 40 A rated current (In) is the continuous load it can carry without overheating — sized for a submain or a heavy branch circuit feeding multiple socket outlets or fixed equipment. The 30 mA residual trip threshold is the standard for personal shock protection in residential and commercial final circuits per IEC 60364. The instantaneous design (no intentional delay) means it trips within milliseconds of a fault — no selectivity with downstream RCCBs unless they are time-delayed (S-type). The installation depth is 70 mm, matching the overall depth. The supply can enter from the top or bottom. Protection class is IP20 with the distribution board installed and conductors connected — suitable for indoor panel use only, not for wet or outdoor locations. The 5SM3314-6KL carries the SENTRON brand and is designed to meet IEC/EN 61008-1 for RCCBs. It is silicon-free, which matters for applications sensitive to silicone outgassing (e.g., in paint shops or certain electronics assembly).","metaTitle":"Siemens 5SM3314-6KL SENTRON RCCB, 2-pole Type A, 40 A 30 mA","metaDescription":"Siemens 5SM3314-6KL SENTRON 2-pole RCCB, Type A, 40 A rated current, 30 mA trip sensitivity, 230 V AC, 10 kA SCCR.

Availability and current pricing are confirmed at the time of quotation — no stock or price figures are published here."},{"question":"What is the difference between 5SM3314-6KL and the 5SL6563-7BB miniature circuit breaker?","answer":"They serve different protection functions. The 5SM3314-6KL is an RCCB that detects earth leakage (30 mA trip), while the 5SL6563-7BB is a miniature circuit breaker (MCB) that protects against overload and short circuit (63 A, C-curve). They are not substitutes; in a panel they are often installed in series — the MCB for overcurrent, the RCCB for earth fault. The 5SM3314-6KL is 2-pole (L+N), the 5SL6563-7BB is 1P+N. Both share the same 36 mm width and 70 mm installation depth, so they fit the same DIN-rail footprint."},{"question":"What compliance documentation does Siemens provide for 5SM3314-6KL?","answer":"Siemens provides a Declaration of Conformity (CE) and typically supports RoHS and REACH compliance declarations for the SENTRON 5SM3 series. The product is designed to meet IEC/EN 61008-1.
