POLYSWITCH 22W RXE109
Code: 8205196
- Cost-effective speaker protection is achieved through detailed specifications, ensuring precise selection for optimal safeguarding. Polyswitch protectors, utilizing conductive polymers, function as resettable solid-state circuit breakers.
**RN3464**
Polyswitches offer protection against electrical overloads, safeguarding speakers in most scenarios. However, they do not prevent mechanical overloads. Device selection should be based on the trip power rating in watts. For instance, to protect a tweeter rated at 10 watts RMS and 8 ohms, choose an RXE075 device. When uncertain, opt for a conservative approach. Some experimentation may be required due to the variability of music signals. Connect the device in series with the speakers for protection.
**Functionality**
When the protector's operating current is exceeded, the device's interior partially melts, increasing volume and resistance significantly, thereby reducing current. The device remains in this state as long as the current is maintained due to elevated temperature. Once the current is removed, the device quickly resets, restoring its low resistance value.
**Voltage Ratings**
- RN3460 and RN3462: 60 volts; others: 50 volts.
- Part No: RXE075
- Trip 4 Ohms: 5.1 watts
- Trip 6 Ohms: 7.7 watts
- Trip 8 Ohms: 10.2 watts
- Trip Current: 1.13 amps
