Product details

The Siemens SENTRON 5SL1216-7MB is a 2-pole miniature circuit breaker with C-curve tripping characteristic, rated at 16 A. Rated for single-phase operation at 253 V AC and multi-phase up to 440 V AC, 50/60 Hz, it fits standard 230/400 V networks. The 2-pole design switches both line and neutral, making it suitable for single-phase final circuits where disconnecting both conductors is required.

Panel fit and environment

Occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and 70 mm installation depth behind the panel. Mounting position is unrestricted. Rated for ambient temperatures from -40 °C to 75 °C, overvoltage category III, pollution degree 2.

Frequently asked questions

What is the breaking capacity of 5SL1216-7MB?

Rated breaking capacity is 3 kA according to IEC 60947-2. This is the standard rating for residential and light commercial distribution boards where fault levels are modest.

What is the difference between 5SL1216-7MB and the 3-pole 5SL4363-7?

The 5SL4363-7 is a 3-pole, 63 A, C-curve MCB with a 10 kA breaking capacity per both IEC 60947-2 and EN 60898, and a 10 000-cycle mechanical life. The 5SL1216-7MB is 2-pole, 16 A, 3 kA, with a 4 000-cycle life. The 5SL4363-7 is physically wider (3 MW vs 2 MW) and is intended for higher-current three-phase sub-feeds, not single-phase final circuits. They are not drop-in replacements; the panel cutout and busbar arrangement differ.

Where can I buy 5SL1216-7MB?
