General rules for installation:
Important note:Limiter designed to comply ONLY with IEC60079-0: 2011 (Explosive atmospheres, general requirements), § 26.5.1.2 and IEC 60079-15: 2010 (Explosive atmospheres, Equipment protection by type of protection “n”) § 19 ; 22.5.1 ; 22.5.2 ; 22.5.3.1 ; 22.5.3.2 and 22.5.3.3, when R32 mildly flammable refrigerant classed A2L upon Ashrae 34 and ISO 817, as found in air conditioning and heat pumps, may be present (See EN6.335-2-40)

Approval: TÜV Test report TÜV GC/70269203

Housing: IP65 aluminum, epoxy potted,many different dimensions, see drawings

Temperature sensing element: Miniature bimetal disc, not current sensitive

Electrical connection: Two PVC insulated wires, 0.75mm², T105°C (221°F). H05VVF 300V/500V. Wire ends with crimped terminals.

Ground: By the enclosure body

Adjustment: These limiters are factory calibrated, with no adjustment possible by user. Calibration values are checked on it before encapsulation.

Mounting: Surface or through wall

Response time: These limiters are not designed to respond quickly if the temperature rise rate is higher than 1°C per minute.

Contacts: Single pole snap action contact, open or close by temperature rise

Electrical rating: 5A 250V resistive (100,000 cycles). Suitable for power control, remote control of relay coils or PLCs circuits.

Option: On request rating up to 9A 250V with 1.5mm² wires (Need certification testing)
