The APM1L0LPMN4 is a line paralleling power module from the Altivar Process Modular range.
Cabinet-mount only — no standalone enclosure. The module itself is IP00, but when integrated into a cabinet it can achieve IP21 or IP66 depending on the cabinet build. UL Type 1 or Type 12 ratings apply with proper cabinet integration, so the enclosure choice drives the final protection level. Operating temperature range is -10…40 °C without derating; up to 50 °C with a derating factor. Storage range is -40…70 °C. Altitude derating starts above 1000 m, with operation possible up to 4800 m. The module is rated for pollution degree 2 per IEC 61800-5-1 and carries chemical resistance class 3C3 and dust class 3S3 per IEC 60721-3-3 — relevant if the environment has aggressive atmospheres or particulate. EMC immunity is specified at test level 3 for electrostatic discharge, radiated RF, and conducted RF; surge immunity at level 3; electrical fast transient/burst at level 4. That puts it in the range for industrial environments with significant drive EMI — the kind of noise you get from large VFDs and switching power supplies in the same panel.
The module is CE-marked and complies with UL 61800-5-1, IEC 61800-3, IEC 61800-5-1, IEC 61000-3-12, IEC 60721-3, IEC 61508, and IEC 13849-1. For functional safety (SIL) documentation, the IEC 61508 and IEC 13849-1 references indicate the design supports safety-related applications; the specific safety manual and SIL declaration are part of the Altivar Process Modular documentation set.
