Mounting position is unrestricted — horizontal, vertical, or flat — which simplifies panel layout when gland plates or busbar runs constrain orientation. Screw terminals accept solid or stranded conductors from 0.75 to 25 mm², with a tightening torque of 2.5 to 3 N·m. The housing is sealable, halogen-free, and silicon-free, so it's suitable for environments where off-gassing or contamination is a concern.

Frequently asked questions
What is the breaking capacity of 5SL4404-8?
10 kA rated breaking capacity per both EN 60898 and IEC 60947-2, so it safely interrupts fault currents up to that level in a 400 V AC circuit.
Where can I buy 5SL4404-8?
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
What is the difference between 5SL4404-8 and 5SL3120-6MB?
The 5SL4404-8 is a 4-pole, 4 A, D-curve MCB; the 5SL3120-6MB is a different variant — pole count and rating differ. They are not drop-in substitutes without verifying the circuit requirements.
