The DIN rail mount and IP20/IP40 enclosure fit standard distribution panels. The B-curve trips between 3 and 5 times rated current — that's 48 A to 80 A for this 16 A breaker. It's the right characteristic for resistive and small inductive loads where inrush isn't severe; don't pair it with motor starts or transformer primaries that draw a high magnetizing surge, because nuisance tripping will find you at 2 a.m. The 25 kA breaking capacity matches the typical prospective fault level at a secondary distribution board fed by a 400 V transformer up to about 630 kVA. Physical fit: 35 mm wide (2 modules on a DIN rail), 88 mm tall, 69 mm deep. The depth matters when the gland plate is tight — 69 mm is shallow enough for most 80 mm deep enclosures but leaves little room for finger-safe shrouds if you're wiring with ferruled conductors. The Bi-Directional Cylinder Lift terminal accepts both screw-clamp and lift-wire connections; tighten to 2.8 Nm max.","metaTitle":"ABB 2CDS281103R0165 Miniature Circuit Breaker, B, 16A, 440V","metaDescription":"ABB miniature circuit breaker, 2 poles, B-curve, 16 A rated current, 440 V insulation voltage, 25 kA breaking capacity.
