PolySwitch Resettable Devices
Strap Battery Devices
Raychem Circuit Protection, pioneer of polymeric PTC resettable
devices, has developed several material platforms specifically
tailored to help protect battery applications. Each of these
material platforms offers different performance characteristics,
allowing the engineer greater design flexibility. Raychem Circuit
Protection’s battery protection family includes SRP, LTP, LR4,
VTP, VLP, and VLR series, disc, and special application strap
devices.
Benefits

Installation Guidelines for the Strap Family
• Polymeric PTC devices operate by thermal expansion of the conductive polymer. If devices are placed under pressure or installed
in spaces that would prevent thermal expansion, they may not properly protect against fault conditions. Designs must be selected
in such a manner that adequate space is maintained over the life of the product.
• Twisting, bending, or placing the Polymeric PTC device in tension will decrease the ability of the device to protect against electrical
faults. No residual force should remain on device after installation. Mechanical damage to Polymeric PTC chip may affect device
performance and should be avoided.
• Chemical contamination of Polymeric PTC devices should be avoided. Certain greases, solvents, hydraulic fluids, fuels, industrial
cleaning agents, volatile components of adhesives, silicones, and electrolytes can have an adverse effect on device performance.
• Polymeric PTC strap devices are designed to be resistance welded to battery cells or to pack interconnect straps, yet some
precautions must be taken when doing so. In order for the Polymeric PTC device to exhibit its specified performance,
weld placement should be a minimum of 2mm from the edge of the Polymeric PTC chip, weld splatter must not touch the Polymeric
PTC chip, and welding conditions must not heat the Polymeric PTC device above its maximum operating temperature.
• Polymeric PTC strap devices are not designed for applications where reflow onto flex circuits or rigid circuit boards is required.
• The polyester tape on PolySwitch strap devices is intended for marking and indentification purposes only, not for electrical insulation.

Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame.
The devices are intended for protection against occasional overcurrent or overtemperature fault conditions and should not be
used when repeated fault conditions or prolonged trip events are anticipated.
Contamination of the PPTC material with certain silicon based oils or some aggressive solvents can adversely impact the
performance of the devices.
Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic,
thermal, and mechanical procedures for electronic components.
Operation in circuit with a large inductance can generate a circuit voltage (L di / dt ) above the rated voltage of the
PolySwitch resettable device.
