Thermostat Lanberg AK-1505-B Grey

Thermostat Lanberg AK-1505-B Grey is a closed-loop temperature controller designed for rack cabinets and electrical enclosures. Housed in a plastic casing with UL 94 V-0 flammability rating and an IP20 protection level, it monitors ambient temperature using a thermo-bimetallic sensor and switches connected cooling equipment on or off within a 120–250 V AC supply range. The compact device (67.8 × 43 × 97.3 mm) includes mounting options for DIN 35 mm rails and a removable flat mounting ear for flexible RACK installation.

Advantages

The AK-1505-B uses a normally open (NO) snap-action contact actuated by a thermo-bimetallic strip for fast and reliable response to temperature changes. The plastic housing meets UL 94 V-0 vertical flammability requirements, reducing the risk of contributing to fire spread. The thermostat offers multiple mounting options (clips for DIN rail plus a removable powder-coated mounting ear) and includes a set of accessories—terminal block, screws, washers and cable tie—for easier installation and neat cable management.

How to use

Install the thermostat inside the rack or enclosure at a location representative of the internal air temperature. Mount using the rear DIN 35 mm rail clips or the supplied removable mounting ear; the device can be fitted on either side of a vertical rail and rotated 180° if needed. Connect the cooling equipment to the terminal block according to the wiring diagram, ensuring the contact rating and supply voltage match the connected devices. Adjust the temperature setpoint using the front knob so the thermostat closes the circuit and powers the cooling when the ambient temperature exceeds the chosen threshold.

Recommendations

The thermostat is intended for indoor use in ventilated enclosures; avoid exposure to direct water or outdoor conditions. Verify wiring and load limits (terminal block up to 10 A) before connecting high-current devices, and position the sensor away from direct heat sources or vents to ensure accurate temperature control.
