Low Voltage Standoff Insulators:
Suitable for a variety of low-voltage assemblies, the AM4 low-voltage standoff insulator range supplies excellent mechanical strength and electrical insulation.
Post insulators, egg insulators, bobbin insulators, and busbar isolators are all terms used to describe standoff insulators as well.
Our AM4 insulating standoffs come in different heights from 30mm to 60mm, as well as insert sizes of M6 to M12. Heights, thread depths and sizes, maximum tightening torques, cantilever and tensile strengths, and box quantities are all listed on our datasheet or in the table above.
The AM4 insulators have the following properties:
- Halogen Free
- Equipment voltage of up to 1000 VAC / 1500 VDC
- Insulation voltage of up to 1000 VAC / 1500 VDC
- Operating temperature ranging from -20°C up to +130°C (-4°F up to +266°F)
- UL Recognised Component; file number E505645
- Made from UL94-V0 rated, self-extinguishing material
Termate AM4 standoff insulators are manufactured from halogen free glass-reinforced polyamide 6.6 material and contain precision threaded brass alloy inserts for greater corrosion resistance. The injection moulding process we use to manufacture our electrical insulating parts improves overall product quality and design accuracy.
Product testing is critical for any component that will be used in an electrical or mechanical system. Professional, thorough, and independent testing has been performed on the AM4 standoff insulator range to assure efficacy when installed correctly in their intended assembly.
One of the most widely used tests for determining the ability of plastic parts to self-extinguish after the heat source has been removed is UL 94. All Termate low voltage standoffs meet V0 requirements for the UL94 test standard.
AM4 insulating standoff spacers are designed and tested in line with the relevant clauses of IEC / BS EN 61439 for low voltage switchgear and controlgear assemblies. Our standoff insulators have undergone comprehensive testing, including cantilever, torque, and tensile tests, to give you peace of mind that they will fulfil specified ratings when fitted appropriately.
These standoff insulators are designed to hold live busbars and other active conductors as an insulating support, safely and securely, by keeping a gap between two surfaces and is appropriate for assemblies up to 1000 V AC & 1500 V DC. The electrical insulation and mechanical strength of the support are critical in these types of systems.
Here is a list of some of the most common applications for our insulators:
- Electrical panel boards
- Control panels
- Power factor correction
- Distribution boards
Power distribution, rail (rolling stock & trackside), renewable energy, UPS (temporary and emergency power), and data centre power distribution are all examples of sectors where these electrical installations and assemblies are used.
