FAQs
What is an automatic transfer switch and why do I need one?
An automatic transfer switch (ATS) provides redundant power distribution by automatically switching equipment loads between two independent power sources. It eliminates manual failover, protects against single-point power failures, and ensures continuous operation of critical IT equipment in server racks.
Can the AP4421A handle my entire data centre power load?
The AP4421A has a maximum load capacity of 2000VA with 10A rated current per input. It is designed for single-corded equipment in IT racks. For larger installations, you may need multiple units or higher-capacity switches. Consult our sales team for your specific requirements.
What outlets does the AP4421A provide?
The switch provides 12 IEC C13 outlet sockets (the standard three-pin connector used by most IT equipment) and accepts two IEC C14 inputs. This configuration is ideal for distributing power from dual UPS units or power sources to a single rack.
How do I configure and monitor the AP4421A?
The integrated APC NMC3 network management card allows configuration and monitoring via secure Web UI, SNMP (Simple Network Management Protocol), and CLI (command-line interface). It is fully compatible with EcoStruxure IT for centralised infrastructure management.
Is the AP4421A compatible with my existing UPS and infrastructure?
The AP4421A is compatible with compatible sensors (AP9335T, AP9335TH) and mounting kits (AP7768, AP7769). It integrates with EcoStruxure IT platforms and standard 230V single-phase power systems operating at 50/60Hz. Confirm compatibility with your specific setup before purchase.
What is the warranty coverage?
The AP4421A comes with a standard 24-month warranty. APC also offers an extended 5-year warranty option for additional peace of mind and long-term protection.
What are the operating and storage temperature ranges?
The switch operates reliably between -5°C and 45°C, making it suitable for most data centre and server room environments. For storage, it tolerates temperatures from -25°C to 65°C, providing flexibility for transport and off-site storage.
Does the AP4421A require a circuit breaker?
The AP4421A does not include an integrated circuit breaker. It provides automatic transfer functionality without additional protection circuitry. Ensure your input power sources are protected upstream.
