DC rating caps at 72 V. The 18 mm width and 76 mm depth (70 mm installation depth) are standard for a 1-module MCB. Mounts in any position;
Snap-on DIN rail mount, one modular width (18 mm). Sealable means the toggle can be locked in the OFF position with a standard seal wire for lockout/tagout compliance.
