Description
S24 breakers are made in 1P, 1P+N, 2P, 3P and 4P versions with curve C, while the P24 series has 1P and 1P+N with a breaking capacity of 3 kA and 4.5 kA. S24 RCDs have a 30 mA setting and are made 2P and 4P for 25, 40 and 63 A of classes AC and A (6 kA), class B (10 kA), immune A+SI types for electronic loads, and the S24DR2P4030 with automatic reclosing. The residual current breaker with overcurrent protection S24ROA251130 is 1P+N, 25 A, 30 mA, 2 modules. Type 2 surge protective devices (S24LST1N, S24LST3N) are rated for 320 V AC and 15-30 kA, type 1+2 (S24LST3N/12) for 12.5-20-50 kA. S24CM contactors for 25, 40 and 63 A (2P, 4P) have a 230 V coil, S24GM motor protection breakers have ranges of 2.5-4 and 4-6.3 A, and S24BE and S24BM releases are 230 V. Fuse holder disconnectors are 10×38 (500 V, up to 32 A) and 14×51 (690 V, up to 50 A), and 1P-4P busbars of 10 and 16 mm² cross-section are rated for 63 and 80 A. The line also includes time relays (24-hour R24 with a 72 h reserve, astronomical RA2, staircase timer AE16), a class I CONT30R meter for 0.02-80 A, and Ø22 mm buttons, lamps and switches. Standards are EN 60898-1, EN 60947-2, EN 61008-1, EN 60730-2-7 and EN 62053-21.
How to choose
The P24 series is taken when only 1P and 1P+N breakers of 3 kA or 4.5 kA are needed, while S24 covers 1P-4P for 6-63 A. For circuits with electronic loads an A+SI class RCD is better, and where automatic restart is needed, S24DR2P4030 is installed.
